EMULSIFIER FOR WATER-IN-OIL EMULSIONS

摘要

A unique and improved emulsifier for waterin-oil emulsions is provided by heating lecithin for a period of time sufficient to alter its composition such that the improved emulsifier is obtained. For example, the lecithin can be heated at a temperature in the range of from about 100.degree.C to about 250.degree.C for a period of time ranging from about 15 to about 480 minutes. The resultant thermally altered lecithin exhibits improved emulsification characteristics for water-in-oil emulsions. A water-in-oil emulsion comprised of a continuous oil phase, a discontinuous aqueous phase and the thermally altered lecithin exhibits excellent stability and an improved holding capacity with respect to the discontinuous aqueous phase.
